| dc.description.abstract | Field experiments were conducted to evaluate the effects of selected herbicides on Italian ryegrass, forage production, and returns from hard red winter wheat grain. Herbicides included BAY FOE 5043 + metribuzin (4:1 w/w premix), BAY MKH 6562, chlorsulfuron, chlorsulfuron + metsulfuron (5:1 w/w premix), clodinafop, diclofop, MON 37560, pendimethalin, tralkoxydim, and triasulfuron. Italian ryegrass was controlled greater than 90 % by 27 of 39 treatments at one site, and by 20 of 39 treatments at a second site. Grain dockage was reduced by 38 and 36 treatments at the two sites, and grain yield was improved by 35 and 36 treatments. Forage yield was frequently decreased by controlling Italian ryegrass. No treatment decreased forage protein content. Gross returns from wheat grain were not improved over the untreated check by seven treatments at Site 1, and by one treatment at Site 2. resulted in a negative gross retum at Site 1. All treatments other than pendimethalin at 840 g/ha applied 3 days after seeding improved gross returns at both sites. | |
